MOUTH OF DUWAMISH RIVER

Harbor Island is a 400-acre industrial island located in Puget Sound at the mouth of the Duwamish River on the southern edge of Elliott Bay. The island was created around 1905 from sediments dredged from the Duwamish Waterway. Since 1912, the island has been used for commercial and industrial activities, including secondary lead smelting, shipbuilding and repair, bulk petroleum fuel storage, metal fabrication, and containerized cargo shipping. Warehouses, laboratories, and other buildings are located on the island. There are no residences on Harbor Island, but approximately 10,000 people live within one mile of the site. All these residents receive their water from the Seattle public water supply system. Fishermen use the waters around Harbor Island for shellfishing, crabbing, and fishing. Site Responsibility: This site is being addressed through federal, state and potentially responsible parties' actions.
